I COFFEE-MA IING APPARATUS;

Application filed November 28, 1927. serial No. 233,291.

instantaneous and in a clean y and efficient manner. c t p y The present invention is designed asan improvement uponsome of my prior p ents along this line, among others of whic be mentioned Nos. 1,462.5302131-(1 T The present invention ha? 1 character readily applied or load can tion with a coffee pot, an urn or an indii cup.

The present invention also provit the making of one or more cups of coiiee as may be desired, the containers icing adapted to be inter-engaged one with smother, liquid tight. v, v 7

One of the primary objects however,ofthe present inven ion is the provision of a novel form of strainer having provision for keeping the cloth or foraininous material practically taut, so as to prevent sagging thereof in use. s

The strainer is removahly connected w th the container thus providing for its quick and ready removal when desired, when the strainer and the part bvwhich it is carried may be quickly and ea y cleaned, ready for instant use for the making of another cup or quantity of coffee. 7

Other objects and advantages of the inven tion will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.

The invention in its preferred form is clearly illustrated in the accompanying drawings which, with the numerals of reference marked thereon form a' part of this specification, and in which:

Figure 1 is an elevation with parts broken away showing my present. improvement as applied to an individual'cup.

throughout the several views; 7 wiil first c my novelcontainer and its strainer and give a brief description of the mode of use. ,c 7 I .Referingto the drawings, 1 designates a container, or coffee grain compartment or vessel provided with a suitable handle 2, the lower portion of said container in this instance being shown of less diameter, although this is not necessary, while preferred, and this reduced portion 3 is externally shown at i for detachable threaded and liquidtight engagement witii the upstanding flange 5 of the member 6 with threads 7 of which cooperate with and form a liquid tight oint with said threads 4, as will be clearly understood upon reference to F igures 4t and 5. I i 1 The member 6 may be constructed in'any suitable manner of a single piece as shown or I of more or less parts, the functions being the same under all conditions. In the present instance it is shown as having an inwardlyexthe outwardly extending flange -10 on the member 6 upon the upper edge of an individual cup 12, as seen in Figure 1, or of a coffee pot 13 as seen in Figure 4, or, when desired it maybe used in connection with an urn.

enumeralsv of reference indicate like Figure 7 is a cross section of the sanieon Cil The percolator may be readily removed at any time for cleaning or other purpose by simply unscrewlng the member 6, removing the percolator and the latter cleaned, or a be placedupon the container, if desired, to retain the steam which aids materially in the making of the coffee.

In use the container may be placed upon an individual cup, as in Figure 1, or upon the coffee pot 13, as seen in Figure 4, and it it be desired to make more than one cup of coffee or a larger amount of coil'ee than may be made with the one container, I provide additional containers as adapted to snugly fit one Within the other, as seen in said Figure l, the result being obvious.

The percolator may be variously constructed. As shown in Figures 2, 3, 4, 5, 6 and7, it comprises a circular disk 15 of closely woven wire cloth or other :tabric adapted to be received. in the member 6 and firmly grasped along its peripheral margin between the flanges 8 and 9 where the member 6 is screwed tightly upon the screw threads 4 of. the container, and is thus held strongly distended. The fabric may be of silk, cotton, linen or other fibre adapted to be readily cleansed after use.

As shown in Figures 8 and 9, the percolator consists of two disks 11, preterably of metal having large'perttorat-ions 12 to form circular open-work grids, and a disk lt of filter paper introduced and held between the grids, the whole supported between the flanges 8 and 9 as will be understood.

It will be apparent that other modifications and details may be resorted to without dep arting from the spirit of the invention or sacri-v ficing any of its advantages.

VV hat is claimed as new is v 1. In a coitee making device, a container, a supporting member having screw threaded liquid tight removable engagement therewith, and a percolator member supported upon said supporting member and removably held by the container,

2. In. a coffee making apparatus, a flanged member adapted to be supported upon the upper edge of a receptacle, an annular member mounted upon said supporting member, a percolator supported thereby, and a retaining ring secured to the percolator member to hold the same in stretched condition.

. 3. In a coffee making apparatus, a member having a reticulated portion, .a. percolator fabric having a. surrounding edge retained by an annular disposed member, and a clamping member cooperable therewith.

1. A cottee making apparatus comprising a container with screw threaded annular portion at its lower end and'a coooeratin ercolator receiving member, and an intermediate member having the toraminous portion permanently retained in stretchedposition within the first named member.

In a coffee making apparatus,a container with toraminous bottom portion, and an extension tor said container adapted for removable insertion therein to vary the capacity of the container.

6. In a coffee making apparatus, a con-' t ainer supporting member comprising a por- 1- i tron ior removable support upon a receptacle and having an inwardly extended flange, a removable flanged member for cooperation therewith, a percolator cloth with peripheral stretching means, and a member removably supported upon said cloth and said flange.

In testimony whereof I atfix my signature.
